The Village of Aberdeen was a development by Edmund Law Rogers around 1800.[4] The name originated from its mother city, Aberdeen, Scotland, as a result of the close relationship the Rogers family of Baltimore had with their cousin, the Earl of Aberdeen, who became Prime Minister of Great Britain in 1852.[6] The area now known as Aberdeen is a cluster of three communities[7][8]
